MPF Event

The number of balls in play has just changed, and there is at least 1 ball in play.

Note that the number of balls in play is not necessarily the same as the number of balls loose on the playfield. For example, if the player shoots a lock and is watching a cut scene, there is still one ball in play even though there are no balls on the playfield.
